I can't criticise the batteries, I'm just charging them, I'll put them to use then. I can only rate them after a fairly long period of use.
However, I am very satisfied with your service, fast order processing and prompt replies to my queries when the first shipment did not arrive. You sent the second one, which I have received.Verified purchase

After using the batteries for the first time, I am very satisfied. The larger capacity is doing very well. I'm curious how long the NiMh battery will last.

Arvostella voisi vasta melko pitkän käytön jälkeen.
Olen kuitenkin todella tyytyväinen toimintaanne, nopea tilauksen käsittely ja pikaiset vastaukset kyselyihini kun ensimmäinen lähetys ei perille tullut. Lähetitte toisen, jonka olen saanut.Verified purchase

With a little teething problems, the batteries I ordered started to work perfectly. One battery was defective, but was immediately and easily replaced with a new one by SUBTEL. When replacing it, it initially looked as if it would not work either, because I had to re-attach it to the SONY charger several times until the charging LED lights up red. Before that, the LED flashed quickly green-red. It is only to be hoped that the batteries will last as long as possible, which I now assume. In any case, the product is at least as good as the original, only much cheaper!
This review was translated automatically. Source language wasMit ein bisschen Anlaufschwierigkeiten haben die von mir bestellten Akkus einwandfrei zu funktionieren begonnen. Der eine Akku war defekt, wurde aber von der Firma SUBTEL umgehend und ohne Weiteres durch einen neuen ersetzt. Beim Ersatz sah es anfänglich so aus als ob dieser auch nicht funktionieren würde, weil ich ihn mehrmals neu beim SONY Ladegerät auflegen musste bis die Lade-LED rot aufleuchtete. Vorher blinkte die LED schnell grün-rot. Es ist nun nur zu hoffen, dass die Akkus möglichst lange halten, wovon ich nun aber ausgehe. Das Produkt ist jedenfalls mindestens so gut wie das Original nur viel günstiger! -
